Bajang
The Bajang is a vampiric creature from Malaysia. It can be summoned by a sorcerer using the body of a stillborn baby taken from their family. Some claim it to be the male counterpart to a creature called the Langsuir. They can sometimes be bound as a Familiar and contained in a container known as a Tabong, sealed with leaves and a magical charm. If not fed milk and eggs by its owner, it will seek children to consume. It can take the shape of a cat, polecat, or large lizard. If it takes the form of a cat and meows like a baby then that baby is destined to die. They may inflict a mysterious disease on their victims. There is no known method to kill a Bajang, but they can be warded off with certain charms and attacking its controlling sorcerer may stop it.
